India is an agriculture-based country, and agriculture is the backbone of Indian economy. More than half of the population depends upon agriculture. The majority of the farmers rely on conventional farming in comparison to natural or organic farming. To fulfil the food requirement, it is necessary to increase yield and production of crops. Different types of chemical fertilizers are used to increase total yield. Due to the large use of these fertilizers, heavy metal ions increased in the soil which may be toxic to animals and humans. The heavy metals are also present in city waste water (CWW) in toxic amount, and when this polluted water reaches to adjoining areas of the city, it contaminates the soil. When these heavy metals are absorbed by the plants, it may lead to some adverse effect on different growth parameters which directly affects the total yield of the crop. The quantity of these chemicals can be reduced with the help of microbes present in soil or by use of biofertilizers. This book chapter describes the importance of organic farming to maintain sustainable agriculture. |
